Follow the world of humans

Carlos Casteneda has Don Juan state “there is a world of happiness where there is no difference between things, because there is no one there to ask about the difference.  But that is not the world of men.  Some men have the vanity to believe that they live in two worlds, but that is only their vanity.  There is but one world for us.  We are human, and must follow the world of humans contentedly.”
